Bring in updates to roraty encoder driver switching it away from legacy
platform data and over to generic device properties and adding support
for encoders using more than 2 GPIOs. -
When changing the scan rate as part of runtime-resume process we may lose
some of the events, because:1) for gen3 trackpads, the driver must msleep() some time to ensure that
the device is ready to accept next command;2) for gen5 and later trackpads, the queue dumping function will simply
ignore the events when waiting for the set power mode command response.The solution is to keep polling and report those valid events when the set
power mode command is in progress.Signed-off-by: Dudley Du

A dependency on ARCH_SHMOBILE seems to be the best option for sh_keysc:
* For Super H based SoCs: sh_keysc is used on SH_MIGOR, SH_ECOVEC, SH_KFR2R09,
SH_7722_SOLUTION_ENGINE, and SH_7724_SOLUTION_ENGINE, which depend on
either CPU_SUBTYPE_SH7722 or CPU_SUBTYPE_SH7724, and both select
ARCH_SHMOBILE.* For ARM Based SoCs: Since the removal of legacy (non-multiplatform) support
this driver has not been used by any Renesas ARM based SoCs. The Renesas
ARM based SoCs currently select ARCH_SHMOBILE, however, it is planned
that this will no longer be the case.This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.Signed-off-by: Simon Horman

This changes how the used gpios are stored (i.e. a struct gpio_descs
instead of two struct gpio_desc) and as with >2 gpios the states are
numbered differently the function rotary_encoder_get_state returns
unencoded numbers instead of grey encoded numbers before. The latter has
some implications on how the returned value is used and so the change is
bigger than one might expect at first.Signed-off-by: Uwe Kleine-König

Drop support for platform data passed via a C-structure and switch to
device properties instead, which should make the driver compatible with all
platforms: OF, ACPI and static boards. Static boards should use property

The SNVS power key driver has suspend/resume functions that
are accessed using SIMPLE_DEV_PM_OPS, which hide the reference
when CONFIG_PM_SLEEP is not set, resulting in a warning about
unused functions:drivers/input/keyboard/snvs_pwrkey.c:183:12: error: 'imx_snvs_pwrkey_suspend' defined but not used [-Werror=unused-function]
drivers/input/keyboard/snvs_pwrkey.c:194:12: error: 'imx_snvs_pwrkey_resume' defined but not used [-Werror=unused-function]This adds __maybe_unused annotations to let the compiler know

The spear keyboard driver uses #ifdef CONFIG_PM to hide its
power management functions, but then uses references from

Convert to use threaded IRQs to support GPIOs that can sleep.
Protect the irq handler with mutex as it can be triggered from
two different irq lines accessing the same state.This allows using GPIO expanders behind I2C or SPI bus.

The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is
not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer
functionality only, can still be compiled if GPIOLIB is not enabled.If COMPILE_TEST is enabled, relax the dependency on GPIOLIB for the
recently introduced or relaxed symbols TOUCHSCREEN_GOODIX and
TOUCHSCREEN_COLIBRI_VF50.Signed-off-by: Geert Uytterhoeven

Driver for the BYD BTP10463 touchpad, found in PC Specialist `Lafite'
laptops. This patch sends the magic command sequence which causes the
touchpad to stream intellimouse-style packets.Gestures are detected inside the touchpad, and exposed as special
values in the Z component of each packet - absolute coordinates are
not supported, even in the Windows driver. At present, this supports
two-finger vertical and horizontal scrolling, and provides the
framework to expose the other gestures it can recognize.Signed-off-by: Chris Diamand

When using a protocol v2 or v3 hardware, elantech uses the function
elantech_report_semi_mt_data() to report data. This devices are rather
creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid
touch is reported.Anyway, userspace (libinput) is now confused by these (0,0) touches,
and detect them as palm, and rejects them.Commit 3c0213d17a09 ("Input: elantech - fix semi-mt protocol for v3 HW")
was sufficient enough for xf86-input-synaptics and libinput before it has
palm rejection. Now we need to actually tell libinput that this device is
a semi-mt one and it should not rely on the actual values of the 2 touches.Cc: stable@vger.kernel.org

attempted to disable an unsupported key, unfortunately the check is wrong

might end up scheduling on a NULL vmstat_wq. This is really unlikely
but not impossible.Fixes: 373ccbe59270 ("mm, vmstat: allow WQ concurrency to discover memory reclaim doesn't make any progress")
